SOIL SAMPLER, AND GROUND INVESTIGATION DEVICE
PROBLEM TO BE SOLVED: To provide a soil sampler and a ground investigation device suited to a small-scale investigation at a residential district, etc.SOLUTION: A soil sampler includes a soil sampling side cylinder 53C, a piston 60 capable of moving relatively and freely forward and backward in an inner space of the soil sampling side cylinder 53C, and an airtight mechanism that keeps a gap between the soil sampling side cylinder 53C and the piston 60 airtight. The airtight mechanism includes a storage space PX formed on a piston body 61, and an energizing member 62 disposed in the storage space PX. The energizing member 62 is free to switch between a pressing state in which an outer surface of the piston body 61 is pressed against an inner surface of the soil sampling side cylinder 53C through a wall of the storage space PX, and a withdrawn state withdrawn from the pressing state.SELECTED DRAWING: Figure 5
【課題】住宅地のような小規模の地盤調査に適した土壌試料採取具及び地盤調査装置を提供する。【解決手段】土壌サンプラは、採土側シリンダ５３Ｃと、採土側シリンダ５３Ｃの内部空間において相対的に進退自在なピストン６０と、採土側シリンダ５３Ｃ及びピストン６０の隙間を気密状態にする気密機構と、を備える。気密機構は、ピストン本体６１に形成された収容空間ＰＸと、収容空間ＰＸに配された付勢部材６２と、を有する。付勢部材６２は、収容空間ＰＸの壁を介して、ピストン本体６１の外面を採土側シリンダ５３Ｃの内面へ押し当てる押当状態と、押当状態から退避した退避状態と、の間で遷移自在である。【選択図】図５
